영문 초록

Gelidium corneum-gelatin (GCG) blend films containing fermented pollen extract (FPE) were prepared and used as a packaging material of pork loins. Water vapor permeability (WVP) of the film containing FPE was better than the control film, and the film`s antimicrobial activity against Escherichia coli O157:H7 and Listeria monocytogenes increased with increasing FPE concentration. Addition of 0.15% FPE decreased the populations of Escherichia coli O157:H7 and Listeria monocytogenes by 2.98 and 3.68 Log CFU/g, respectively, compared to the control. Pork loin samples were inoculated with E. coli O157:H7 and L. monocytogenes and packed with the film. The samples packed with the GCG film containing 0.15% FPE had a decrease in the populations of E. coli O157:H7 and L. monocytogenes by 1.49 and 1.01 Log CFU/g after 4 d of storage, respectively, compared to the control. The results suggested that shelf life of the pork loins could be extended by packaging with the GCG film containing 0.15% FPE.
